hypovalve hemispherical. Longitudinal
groove does not extend to the antapical
end. Chromatophores yellow. Neasurements:

*The epivalve and the hypovalve are of
equal size, or the former is somewhat
larger. The epivalve is half-ovoid and
symmetrical. The hypovalve hemispherical
and'sinuous. Stigma present. Chromatophores
are light yellow, brown in old specimens.
Cell measures 50 X 40M.
G. pseudopalustre 25.
11 Cells obovoid to oval; the epivalve is
broadly rounded, half-oval. The hypovalve
is thinner, half-oval or even truncatedly
conical, often asymmetrical. Longitudinal
groove extends to the antapical
end. No stigma. 45 x 28-33)1.
G. mirum 26.
2*Epivalve smaller than hypovalve. Cells are more or
less ovoid, slightly asymmetrical. Apex and antapical
end are occasionally broadly rounded; but frequently
the epivalve is convexo-conical and the hypovalve is
